Owner maintenance precautions
Improper or incomplete service may
result in problems. This section gives
instructions only for the maintenance
items that are easy to perform.
As explained earlier in this section, sev-
eral procedures can be done only by a
HYUNDAI authorised repairer with spe-
cial tools.
✽NOTICE
Improper owner maintenance during
the warranty period may affect warran-
ty coverage. For details, read the sepa-
rate Service Passport provided with the
vehicle. If you're unsure about any serv-
icing or maintenance procedure, have it
done by a HYUNDAI authorised repair-
er.
WARNING- Maintenance
work
• Performing maintenance work on
a vehicle can be dangerous. You
can be seriously injured whilst
performing some maintenance
procedures. If you lack sufficient
knowledge and experience or the
proper tools and equipment to do
the work, have it done by a
HYUNDAI authorised repairer.
• Working under the bonnet with
the engine running is dangerous.
It becomes even more dangerous
when you wear jewelry or loose
clothing. These can become
entangled in moving parts and
result in injury. Therefore, if you
must run the engine whilst work-
ing under the bonnet, make cer-
tain that you remove all jewelry
(especially rings, bracelets,
watches, and necklaces) and all
neckties, scarves, and similar
loose clothing before getting
near the engine or cooling fans.
WARNING- Diesel Engine
Never work on injection system
with the engine running or within
30 seconds after shutting off the
engine. High-pressure pump, rail,
injectors and high-pressure pipes
are subject to high pressure even
after the engine stopped. The fuel
jet produced by fuel leaks may
cause serious injury, if it touches
the body. People using pacemakers
should not move than 30cm closer
to the ECU or wiring harness within
the engine room whilst engine is
running, since the high currents in
the electronic engine control sys-
tem produce considerable magnet-
ic fields.

OWNER MAINTENANCE
The following lists are vehicle checks and
inspections that should be performed by
the owner or a HYUNDAI authorised
repairer at the frequencies indicated to
help ensure safe, dependable operation
of your vehicle.
Any adverse conditions should be
brought to the attention of your repairer
as soon as possible.
These Owner Maintenance Checks are
generally not covered by warranties and
you may be charged for labour, parts and
lubricants used.Owner maintenance schedule
When you stop for fuel:
• Check the engine oil level.
• Check the coolant level in coolant
reservoir.
• Check the windscreen washer fluid
level.
• Look for low or under-inflated tyres.
Whilst operating your vehicle:
• Note any changes in the sound of the
exhaust or any smell of exhaust fumes
in the vehicle.
• Check for vibrations in the steering
wheel. Notice any increased steering
effort or looseness in the steering
wheel, or change in its straight-ahead
position.
• Notice if your vehicle constantly turns
slightly or “pulls” to one side when trav-
elling on smooth, level road.
• When stopping, listen and check for
unusual sounds, pulling to one side,
increased brake pedal travel or “hard-
to-push” brake pedal.
• If any slipping or changes in the oper-
ation of your transaxle occurs, check
the transaxle fluid level.
• Check automatic transaxle P (Park)
function.
• Check the parking brake.
• Check for fluid leaks under your vehicle
(water dripping from the air condition-
ing system during or after use is nor-
mal).
WARNING
Be careful when checking your
engine coolant level when the
engine is hot. Scalding hot coolant
and steam may blow out under
pressure. This could cause burns
or other serious injury.

EXPLANATION OF SCHEDULED MAINTENANCE ITEMS
Engine oil and filter
The engine oil and filter should be
changed at the intervals specified in the
maintenance schedule. If the car is being
driven in severe conditions, more fre-
quent oil and filter changes are required.
Drive belts
Inspect all drive belts for evidence of
cuts, cracks, excessive wear or oil satu-
ration and replace if necessary. Drive
belts should be checked periodically for
proper tension and adjusted as neces-
sary.
Fuel filter (cartridge)
A clogged filter can limit the speed at
which the vehicle may be driven, damage
the emission system and cause multiple
issues such as hard starting. If an exces-
sive amount of foreign matter accumu-
lates in the fuel tank, the filter may
require replacement more frequently.
After installing a new filter, run the engine
for several minutes, and check for leaks
at the connections. Fuel filters should be
installed by a HYUNDAI authorised
repairer.
Fuel lines, fuel hoses and con-
nections
Check the fuel lines, fuel hoses and con-
nections for leakage and damage. Have
a HYUNDAI authorised repairer replace
any damaged or leaking parts immedi-
ately.
WARNING - Diesel only
Never work on the injection system
with the engine running or within
30 seconds after shutting off the
engine. High pressure pump, rail,
injectors and high pressure pipes
are subject to high pressure even
after the engine stops. The fuel jet
produced by fuel leaks may cause
serious injury, if it touches the
body. People using pacemakers
should not move more than 30cm
closer to the ECU or wiring harness
within the engine room whilst the
engine is running, since the high
currents in the Common Rail sys-
tem produce considerable magnet-
ic fields.

Maintenance
Vapour hose and fuel filler cap
The vapour hose and fuel filler cap
should be inspected at those intervals
specified in the maintenance schedule.
Make sure that a new vapour hose or fuel
filler cap is correctly replaced.
Vacuum crankcase ventilation
hoses (if equipped)
Inspect the surface of hoses for evidence
of heat and/or mechanical damage. Hard
and brittle rubber, cracking, tears, cuts,
abrasions, and excessive swelling indi-
cate deterioration. Particular attention
should be paid to examine those hose
surfaces nearest to high heat sources,
such as the exhaust manifold.
Inspect the hose routing to assure that
the hoses do not come in contact with
any heat source, sharp edges or moving
component which might cause heat dam-
age or mechanical wear. Inspect all hose
connections, such as clamps and cou-
plings, to make sure they are secure, and
that no leaks are present. Hoses should
be replaced immediately if there is any
evidence of deterioration or damage.
Air cleaner filter
A Genuine HYUNDAI air cleaner filter is
recommended when the filter is
replaced.
Spark plugs (for petrol engine)
Make sure to install new spark plugs of
the correct heat range.
Valve clearance (if equipped)
Inspect for excessive valve noise and/or
engine vibration and adjust if necessary.
A HYUNDAI authorised repairer should
perform the operation.
Cooling system
Check cooling system components, such
as radiator, coolant reservoir, hoses and
connections for leakage and damage.
Replace any damaged parts.
Coolant
The coolant should be changed at the
intervals specified in the maintenance
schedule.
Manual transaxle fluid
(if equipped)
Inspect the manual transaxle fluid
according to the maintenance schedule.

FUEL FILTER (FOR DIESEL)
Draining water from the fuel filter
The fuel filter for diesel engine plays an
important role of separating water from
fuel and accumulating the water in its
bottom.
If water accumulates in the fuel filter, the
warning light comes on when the ignition
switch is in the ON position.
If this warning light illuminates,
take your car to a HYUNDAI
authorised repairer and have
the water drained and
checked.
Extracting air from the fuel filter
If you drove until you have no fuel left or
if you replaced the fuel filter, be sure to
extract air in the fuel system as it makes
you difficult to start the engine.
1. Remove the air extract nozzle cap on
the fuel filter.
2. Pump up and down until the fuel flows
out of the plug opening.
✽NOTICE
• Use cloths when you extract air so that
the fuel is not sprayed around.
• Clean the fuel around the fuel filter or
the injection pump before starting the
engine to prevent fire.
• Finally, check each part if the fuel is
leaking.
Fuel filter cartridge replacement
✽NOTICE
When replacing the fuel filter cartridge,
use HYUNDAI genuine parts.
CAUTION
If the water accumulated in the fuel
filter is not drained at proper times,
damages to the major parts such as
the fuel system can be caused by
water permeation in the fuel filter.

CAUTION
• Underinflation also results in
excessive wear, poor handling
and reduced fuel economy.
Wheel deformation also is
possible. Keep your tyre pres-
sures at the proper levels. If a
tyre frequently needs refilling,
have it checked by a HYUNDAI
authorised repairer.
• Overinflation produces a
harsh ride, excessive wear at
the centre of the tyre tread,
and a greater possibility of
damage from road hazards.
TYRES AND WHEELS
Tyre care
For proper maintenance, safety, and
maximum fuel economy, you must
always maintain recommended tyre
inflation pressures and stay within
the load limits and weight distribution
recommended for your vehicle.
Recommended cold tyre inflation
pressures
All tyre pressures (including the
spare) should be checked when the
tyres are cold. “Cold Tyres” means
the vehicle has not been driven for at
least three hours or driven less than
one mile (1.6 km).
Recommended pressures must be
maintained for the best ride, top vehi-
cle handling, and minimum tyre
wear.
For recommended inflation pressure,
refer to “Tyre and wheels” in section
8.All specifications (sizes and pres-
sures) can be found on a label
attached to the vehicle.
WARNING -Tyre underin-
flation
Severe underinflation (10 psi
(0.7 bar) or more) can lead to
severe heat build-up, causing
blowouts, tread separation and
other tyre failures that can
result in the loss of vehicle con-
trol leading to severe injury or
death. This risk is much higher
on hot days and when driving
for long periods at high speeds.
